"Growing up I always thought I would end up in pediatrics like my dad. It only took one call as a medical student at the University of Iowa to convince me that surgery was my future. Now I'm back home in Eastern Iowa and am excited to work at the UI Hospitals and Clinics where it all began." — Peter Nau
